From the official King message board:
I asked Steve last week if there was any update on the TOC and got this response: ".....the final table of contents hasn’t been decided, either the stories or the order, but that one of the longer ones has never
been published in this country, and some not at all."
Sounds like he's talking about Bad Little Kid to me. It was originally published in France and Germany, and is optioned for a film by Laurent Bouzereau and his production company, NedlandMedia Inc.
UPDATE: King has also said that UR will be in this book.
